Scientists regenerate neural pathways in mice with cells from rats
Two independent research teams have successfully regenerated mouse brain circuits in mice using neurons grown from rat stem cells. Both studies, published April 25 in the journal Cell, offer valuable insights into how brain tissue forms and present n.....»»
Shaping the future of polymer nanocarriers
Scientists have taken a significant step towards the development of tailor-made chiral nanocarriers with controllable release properties. These nanocarriers, inspired by nature's helical molecules like DNA and proteins, hold immense potential for tar.....»»
Researchers discover MAPK20-ATG6 link in tomato pollen vitality
Pollen development in flowering plants is a complex process involving multiple genetic and physiological pathways. Previous studies have highlighted the importance of mitogen-activated protein kinases (MAPKs) in various plant developmental stages......»»
Boosting "natural killer" cell activity could improve cancer therapy
Yale researchers have uncovered a way to make a type of white blood cells known as natural killer cells—which kill infected, damaged, or malignant cells in the body—more effective against cancer. The approach, they say, could enable new treatment.....»»
Using supercomputer researchers discover new clues to improving fusion confinement
Nuclear fusion—when two nuclei combine to form a new nucleus, thereby releasing energy—may be the clean, reliable, limitless power source of the future. But first, scientists must learn how to control its production......»»
Quantum annealer improves understanding of quantum many-body systems
Physicists have long been pursuing the idea of simulating quantum particles with a computer that is itself made up of quantum particles. This is exactly what scientists at Forschungszentrum Jülich have done together with colleagues from Slovenia......»»
Jupiter"s upper atmosphere surprises astronomers
Using the NASA/ESA/CSA James Webb Space Telescope, scientists observed the region above Jupiter's iconic Great Red Spot to discover a variety of previously unseen features. The region, previously believed to be unremarkable in nature, hosts a variety.....»»
Marine cloud brightening models show unexpected consequences of geoengineering
A combined team of Earth scientists and climate specialists at the University of California San Diego and the National Center for Atmospheric Research has found via modeling that geoengineering projects such as marine cloud brightening can have unexp.....»»
World not ready for climate change-fueled wildfires: Experts
The world is unprepared for the increasing ferocity of wildfires turbocharged by climate change, scientists say, as blazes from North America to Europe greet the northern hemisphere summer in the hottest year on record......»»
New tipping point discovered beneath the Antarctic ice sheet
A new and worrying way that large ice sheets can melt has been characterized by scientists for the first time. The research focuses on how relatively warm seawater can lap at the underside of ground-based ice, which can accelerate the movement of the.....»»
Scientists identify safe havens we must preserve to prevent "the sixth great extinction of life on Earth"
In a new article, a coalition of conservationists and researchers have shown how we can protect Earth's remaining biodiversity by conserving just a tiny percentage of the planet's surface. This affordable, achievable plan would make it possible for u.....»»
Using sound waves, scientists develop findings that challenge standard theories of solar convection
A team of solar physicists at NYU Abu Dhabi's Center for Astrophysics and Space Science (CASS), led by Research Scientist Chris S. Hanson, Ph.D., has revealed the interior structure of the sun's supergranules, a flow structure that transports heat fr.....»»
Geologists expect Chang"e-6 lunar surface samples to contain volcanic rock and impact ejecta
On June 25, China's Chang'e-6 (CE-6) lunar probe is set to return to Earth, carrying the first surface samples collected from the farside of the moon. In anticipation of this historic event, scientists from the Institute of Geology and Geophysics at.....»»
Indigenous data sovereignty can help save British Columbia"s wild salmon
Non-Indigenous scientists increasingly realize that Indigenous data are key to solving today's environmental challenges......»»
What the 3.2 million-year-old Lucy fossil reveals about nudity and shame
Fifty years ago, scientists discovered a nearly complete fossilized skull and hundreds of pieces of bone of a 3.2-million-year-old female specimen of the genus Australopithecus afarensis, often described as "the mother of us all." During a celebratio.....»»
Space radiation can damage satellites—next-generation material could self-heal when exposed to cosmic rays
The space environment is harsh and full of extreme radiation. Scientists designing spacecraft and satellites need materials that can withstand these conditions......»»
Genetic switch in plants can turn simple spoon-shaped leaves into complex leaves with leaflets
The diversity of forms of living organisms is enormous. But how the individual cells together coordinate the formation of organs and tissues in complex organisms is still an open question......»»
3D maps of diseased tissues at subcellular precision
Researchers in the Systems Biology Lab of Professor Nikolaus Rajewsky, at the Max Delbrück Center, have developed a spatial transcriptomics platform, called Open-ST, that enables scientists to reconstruct gene expression in cells within a tissue in.....»»
Study pushes understanding of how cells migrate
Interactions between two key structures within cells help establish the front-to-back "polarity" that is essential to cell migration, according to a new study by Weill Cornell Medicine researchers......»»
Scientists explore the vast reservoir of dissolved organic matter in oceans
Few things last very long in the world of the open oceans, it would seem. In the light-filled surface layer, microscopic algae convert carbon dioxide and water into biomass via photosynthesis. Individual cells vanish in a matter of hours or days, ing.....»»
Saturday Citations: Bulking tips for black holes; microbes influence drinking; new dinosaur just dropped
What did scientists do this week? Exactly four things, all of which are summarized below......»»
